I have a WP_Query which contains data that I want to loop over on the page:
$query_posts_for_board_game = new WP_Query(get_posts(array(
'post_type' => $mm_custom_post_types,
'numberposts' => 20,
'meta_query' => array(
array(
'key' => array('board_game', 'board_games'),
'value' => get_the_ID(),
'compare' => 'LIKE'
)
)
)));
When I var_dump it I can see that it has the data in the query and query_vars properties but when I loop over it using the $query_posts_for_board_game->have_posts() method nothing is output. This code simply prints the else block.
<?php if($query_posts_for_board_game->have_posts()): ?>
<?php while ($query_posts_for_board_game->have_posts()) : $query_posts_for_board_game->the_post(); ?>
<?php get_template_part('template-parts/layouts/content', 'b1' ); ?>
<?php endwhile; ?>
<?php else : ?>
<?php get_template_part('template-parts/layouts/content-none' ); ?>
<?php endif;?>
If I remove the call to WP_Query and just use get_posts I'm able to loop over it with a standard for loop, but then the nested templates can't take advantage of $post like they would with a normal loop:
<?php
// If there are posts
if ($posts_for_board_game) :
// Loop the posts
foreach ($posts_for_board_game as $board_game_post) :
?>
<?php echo $board_game_post->post_title . '<br />'; ?>
<?php
endforeach;
wp_reset_postdata();
?>
<?php endif; ?>
I seem to recall that this is because my custom query isn’t part of “the query”. Is there a way I can override “the query” so that my content can be output? Can I simply move my query further down the page after the other items are output?
I solved it! I'm sort of shocked that it was as easy as this.
I left the WP_Query in place, just like in the first query above. Then in my loop I simply changed the name of the iterator to $post and it started working. Here's the complete code for anyone else who has this question.
$query_posts_for_board_game = new WP_Query(get_posts(array(
'post_type' => $mm_custom_post_types,
'numberposts' => 20,
'meta_query' => array(
array(
'key' => array('board_game', 'board_games'),
'value' => get_the_ID(),
'compare' => 'LIKE'
)
)
)));
$posts_for_board_games = $query_posts_for_board_game->query;
and the output:
<?php if($posts_for_board_games): ?>
<?php foreach ($posts_for_board_games as $post): ?>
<?php get_template_part('template-parts/layouts/content', 'b1' ); ?>
<?php
endforeach;
wp_reset_postdata();
?>
<?php else: ?>
<?php get_template_part('template-parts/layouts/content-none' ); ?>
<?php endif;?>
I'm a little annoyed that I had to use an intermediate variable, to get at the query contents, but I'm fine with this code.

I'm trying to use get_field to return a simple text field and it returns empty for some reason. A field itself is where it should be and there is text in it, so that part is all set. This PHP code is loaded via php snippet, post thumbnail for example, shows up perfectly. So everything works except for ACF field value.
<div class="your-class">
<?php
$args = array(
'post_type' => 'home_test',
'posts_per_page' => -1,
'orderby' => 'name',
'order' => 'ASC',
);
$the_query = new WP_Query($args);
$brand = get_posts($args);
foreach ($brand as $post) {
setup_postdata($post);
$thumbnail = get_the_post_thumbnail_url($post->ID, 'full');
$homelinkvalue = get_field("home_brand_link");
if (!$thumbnail)
continue;
?>
<div>
<p><?php echo $homelinkvalue; ?></p><img src="<?php echo $thumbnail; ?>">
</div>
<?php
}
wp_reset_postdata();
?>
</div>
I think the issue is that you are mixing together a custom post loop (your foreach and setup_postdata()) but then are using functions like get_field(), which make use of the global post object. In this case, get_field() tries to lookup the field value by checking against the global $post, but it has not been properly set. See warning here about setup_postdata($post):
You must pass a reference to the global $post variable, otherwise functions like the_title() don't work properly.
You can implement this in your code with a slight modification:
global $post;
foreach ($brand as $currPost) {
$post = $currPost;
setup_postdata($post);
// Rest of code as normal
}
Or, since get_field() can accept a specific post as an argument instead of automatically using the global one, you could change:
$homelinkvalue = get_field("home_brand_link");
to:
$homelinkvalue = get_field("home_brand_link",$post->ID);
Side note: Normally, the recommended way to iterate posts is with the special "WP loop" pattern, something like:
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<!-- Do something -->
<?php endwhile; ?>
Using the above pattern automatically sets the global $post variable as it loops through, which allows devs to use functions like get_field() without having to worry about explicitly passing in a specific post; makes things a bit easier.
Try this one:
<div class="your-class">
<?php
$args = array(
'post_type' => 'home_test',
'posts_per_page' => -1,
'orderby' => 'name',
'order' => 'ASC',
);
$the_query = new WP_Query( $args );
if ($the_query->have_posts) :
while($the_query->have_posts) : $the_query->the_post();
?>
<div>
<p><?php the_field( "home_brand_link" ); ?></p>
<img src="<?php the_post_thumbnail_url(); ?>">
</div>
<?php
endwhile;
wp_reset_postdata();
endif;
?>
</div>
In wordpress, using the CTU plugin, I made a custom post type called apartments with a field called available. I only want to target any post with available=yes. How would I do this? I tried the_post('available=yes')
<?php
$args = array(
'post_type' => 'apartment'
);
$the_query = new WP_Query( $args );
?>
<?php if( have_posts()): ?>
<?php while ($the_query->have_posts()): ?>
<?php $the_query->the_post(); ?>
<?php $the_field('available'); ?>
<?php endwhile; ?>
<?php else: ?>
<?php endif; ?>
i think the simplest solution is:
1. In your custom taxonomy create a term called available
2. add this to your custom query
$args = array(
'post_type' => 'apartment',
'category_name' => 'available'
);
I have an events page displaying an 'events' custom post type. At the top of the page I have 2 upcoming posts in an upcoming event list and then at the bottom I have 3 past events in a past events list. Posts are displayed in each section based on if an 'event date' custom field is in the past or not. The past events uses WP page navi plugin to paginate the posts. 'posts_per_page' is set at one as a test.
There should be 3 pages that have 1 past post displayed on them, respectively. Unfortunately, the pagination shows 5 pages, the first two have no posts displayed on them, as if the posts from the upcoming posts lists are behaving as ghosts. I have removed the upcoming posts list as a test but this makes no difference.
Does anyone know any reason for this? I have no idea. Thanks.
<?php
$temp_post = $post; // Store the Page the Post
// Get the current date
$current_date = date('M d, Y', time());
$current_date = strtotime( $current_date );
$wp_query= null;
$wp_query = new WP_Query();
$args = array( 'post_type' => 'events','posts_per_page' => 1,'paged' => $paged,'meta_key' => 'event_date', 'orderby' => 'meta_value_num', 'order' => 'DESC');
$wp_query->query( $args );
if ( $wp_query->have_posts() ) :
while ( $wp_query->have_posts() ) : $wp_query->the_post();
// Get the date custom field
$post_date = get_field('event_date');
$post_date = strtotime( $post_date );
// If older than post date, don't show it
if( $current_date > $post_date ): ?>
MY POST CONTENT GOES HERE
<?php endif; // END DATE FILTER ?>
<?php endwhile; //END LOOP ?>
<?php /* Start wp-pagenavi support */ ?>
<?php if(function_exists('wp_pagenavi') ) :
echo '<nav class="pag">'; ?>
<?php wp_pagenavi(); ?>
<?php echo '</nav>'; ?>
<?php else: ?>
<?php twentyeleven_content_nav( 'nav-below' ); ?>
<?php endif; ?><?php /* End wp-pagenavi support */ ?>
<?php endif; ?>
<?php $post = $temp_post; // Reset the Post ?>
It's acting as ghost because you are not showing it. You are showing the navigation in the bottom of page. The query returns 5 page, so navigation would be for 5 page.
But you aren't showing the post, if it doesn't meet this condition
// If older than post date, don't show it
if( $current_date > $post_date ): ?>
That's why those posts are not showing. Remove that condition and you will see that all the posts are showing as it should.
If you want to display pagination this way, you would have to limit the number of returned post from query itself.
Thanks a lot, I managed to work it out with a push in the right direction.
// Get the current date
$current_date = date('Ymd', time());
$wp_query= null;
$wp_query = new WP_Query();
$args = array(
'post_type' => 'events',
'posts_per_page' => 1,
'paged' => $paged,
'orderby' => 'meta_value_num',
'order' => 'DESC',
'meta_key' => 'event_date',
'meta_query' => array(
array(
'key' => 'event_date',
'value' => $current_date,
'compare' => '<',
'type' => 'CHAR'
)
)
);
$wp_query->query( $args );
if ( $wp_query->have_posts() ) :
while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
MY POST CONTENT HERE
<?php //endif; // END DATE FILTER ?>
<?php endwhile; //END LOOP ?>
<?php /* Start wp-pagenavi support */ ?>
<?php if(function_exists('wp_pagenavi') ) :
echo '<nav class="pag">'; ?>
<?php wp_pagenavi(); ?>
<?php echo '</nav>'; ?>
<?php endif; ?><?php /* End wp-pagenavi support */ ?>
<?php endif; ?>
Thing is, In the homepage of my theme, I want to show post from different category in Different Div. Each DIV will contain 3 post from a category. I need a loop that can pick last 3 post from a specific Category. Can't find any suitable ans for it.
To explain things more easily, here is a demo picture of the Content section,
http://i.imgur.com/5QSzAIS.png
It will be a great help, if someone help me with the code !
<?php query_posts('cat=10&posts_per_page=3'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; endif; ?>
This should get you started. You need to use this code twice. Where it says cat=10, you should enter your category ID (you can check this when you click on a Category from the admin panel, the the browser it will show something like this http://yourwebsite.com/wp-admin/edit-tags.php?action=edit&taxonomy=category&tag_ID=4&post_type=post)
Where it says tag_ID is the ID of your category.
I'm currently using a different method on a page of the site I'm building which allows me to run multiple loops in one page and specify the category for each one. This method I personally like better as it is more straightforward to me, and I can define the category with the slug instead of the ID.
Instead of using have_posts() and such, you use WP_Query() after defining your array and then wp_reset_postdata() to end your loop. The benefit is that you can keep running loops this way.
I'm also loading the data from custom fields in my posts using get_post_meta, but this method will work without that stuff.
<div class="audioGrid">
<?php
$args = array( 'post_type' => 'post',
'category_name' => 'audio',
'posts_per_page' => 3,
'order' => 'DESC' );
$query1 = new WP_Query($args);
while ( $query1->have_posts() ) {
$query1->the_post();
?>
<div id="<?php echo( basename(get_permalink()) ); ?>" class="grid_item">
<?php the_post_thumbnail( 'audio-thumb' ); ?>
<h3><?php the_title(); ?></h3>
<p><?php echo get_post_meta($post->ID, 'post_description', true); ?></p>
<a target="blank" href="<?php echo get_post_meta($post->ID, 'audio_link', true); ?>"></a>
</div>
<?php the_content(); ?>
<?php } ?>
</div> <?php // end Audio Grid ?>
<?php wp_reset_postdata(); ?>
<div class="videoGrid">
<?php
$args2 = array( 'post_type' => 'post',
'category_name' => 'video',
'posts_per_page' => 3,
'order' => 'DESC' );
$query2 = new WP_Query($args2);
while ( $query2->have_posts() ) {
$query2->the_post();
?>
<div id="<?php echo( basename(get_permalink()) ); ?>" class="grid_item">
<?php the_post_thumbnail( 'video-thumb' ); ?>
<h3><?php the_title(); ?></h3>
<p><?php echo get_post_meta($post->ID, 'post_description', true); ?></p>
<a target="blank" href="<?php echo get_post_meta($post->ID, 'video_link', true); ?>"></a>
</div>
<?php the_content(); ?>
<?php } ?>
</div> <?php // end Video Grid ?>
<?php wp_reset_postdata(); ?>
Another cool thing I'm doing is using a custom field to define the order of things and using meta_key and meta_value_num to get that number and force the order how I want, and since this site isn't complicated, defining the order this way is convenient. I just use leading zeroes to make it easy: 001, 002, 003, etc
<?php
$args2 = array( 'post_type' => 'post',
'category_name' => 'video',
'posts_per_page' => 3,
'meta_key' => 'video_order',
'orderby' => 'meta_value_num',
'order' => 'ASC' );
$query2 = new WP_Query($args2);
while ( $query2->have_posts() ) {
$query2->the_post();
?>
Anyway, hope this helps if you need to use multiple loops to pull posts from different categories.
I have a custom post type named "audio". To display all the posts in a page I wrote the code below, but it does not work.
<?php
$post_type = "audioes";//post type names
echo "djnbfj";
$post_type->the_post();
// The Query
$the_query = new WP_Query( array(
'post_type' => $post_type,
'orderby' => 'post_date',
'order' => 'DESC',
'showposts' => 1,
));
// The Loop
?>
<?php
while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<div class="issue-content">
<?php get_template_part('includes/breadcrumbs', 'page'); ?>
<?php if ( has_post_thumbnail() ) { the_post_thumbnail();}
get_template_part('loop-audio', 'page');
?>
</div><!--issue-content-->
<?php endwhile; ?>
</div> <!-- end #left_area -->
How can i got the posts type i want the custom one written above.
Is the post type called "audio" or "audioes"? Your $post_type variable is set to "audioes".
I'm not sure what the get_template_part lines or the echo line is doing, but the below code should display your post type. You also have the post type name as "audioes" in your code, but you state that the name is "audio". Try the code below, but if the post type is named "audioes" then you'll need to change that in my code below. You can wrap additional divs, spans, or other HTML tags around <?php the_post_thumbnail(); ?> and <?php the_content(); ?> to give them CSS styles is you wish to.
<?php query_posts(array('post_type' => 'audio', 'posts_per_page' => 1, 'orderby' => 'post_date', 'order' => 'DESC')); ?>
<?php while (have_posts()) : the_post(); ?>
<div class="issue-content">
<?php the_post_thumbnail(); ?>
<?php the_content(); ?>
</div>
<?php endwhile; wp_reset_query(); ?>
